- One mole of Gold (Au) atom has a mass of 197 g. We know that the density of gold is 19.30 g/cm3 in room temperature. Using those numbers, answer the following questions: a) What is the mass of a single gold atom in kg? b) Assume that gold atoms sit in a perfect cubic crystal structure. Estimate the distance between two gold atoms in meters. c) If we have a gold cube of 6 cm on each side, how many atoms can we fit along the edge of each side of the cube? d) What would be the mass, in kilograms, of the gold cube we discussed in part (c) (measuring 6 cm on each side)?Solve it correctly please. I will rate accordingly with multiple votes.In the process of using the scientific method, a researcher: O Directly tests both the null and alternative hypotheses. O Directly tests only the alternative hypothesis because this is the hypothesis of interest. O Directly tests only the null hypothesis because this is the hypothesis of interest. O Directly tests only the null hypothesis because the null hypothesis leads to a specific prediction that can be compared with data. O Can not directly test either hypothesis.
- For the remaining questions, you need to use Figure 1.4 to obtain the necessary orders of magnitude of lengths, masses, and times.About how many floating-point operations can a supercomputer perform each year?I just want explanations like the equations I need to use because I'm not being taught how to solve theseAn Olympic-size swimming pool is 50 m long, 25 m wide, and 2 m deep. In terms of volume, this pool, when full, holds how many kilogallons of water? Use the following equivalences: 1 gallon = 3.8 L 1 kilogallon = 103 gallon 1 L = 103 mL for water: 1 mL = 1 cm3 1 m = 100 cm [Numerical Problem: Just write the numerical answer without units. Express your answer to 2 significant figures in standard notation]
